struggle in adding taxonomy to feature table

Dear all:

I’m a beginner of QIIME2. I have exported feature-table.biom and I want to add taxonomy.tsv to the table.I have tried following command:
biom add-metadata -i exported_rarefied_table/feature-table.biom -o table-with-taxonomy.biom --observation-metadata-fp taxonomy.tsv --sc-separated taxonomy --observation-header taxnomy
biom convert -i table-with-taxonomy.biom -o table-with-taxonomy.tsv --to-tsv --header-key taxonomy
I got table-with-taxonomy.tsv at last, but the table just have a head of taxonomy, the following data is empty.

I’m wondering what’s wrong with my command.

Thanks!

Hi @Jing,
I have a mini-tutorial here for something I did a while back and in it has instructions on how to add taxonomy to your biom file. Might be of use
